Product Description
C4384678 exhaust pressure sensor is a key electronic sensing component for ISZ heavy-duty diesel engine exhaust and emission control system. It measures the pressure of exhaust gas inside the exhaust pipeline, converts pressure changes into electrical signals and transmits data to the engine ECU. The ECU uses these readings to adjust the working status of the exhaust treatment system, optimize exhaust gas recirculation and DPF regeneration process. If this sensor fails, the vehicle may trigger emission fault codes, suffer from poor power output, increased fuel consumption and even enter engine derate mode. It will not only reduce transport efficiency, but also cause the vehicle to fail emission inspection. For long-haul heavy trucks, maintaining normal exhaust pressure monitoring is vital to keep the emission system working properly. Key features: High precision pressure sensitive chip, stable signal transmission, robust anti-vibration housing, waterproof and dustproof connector, wide working temperature range, corrosion-resistant pressure port, OEM plug structure for direct fit. Product Advantages: Full signal calibration before shipment; strong anti-interference capability against harsh engine electromagnetic environment; stable performance under high-temperature exhaust surroundings; matches original mounting position and connector; convenient for maintenance and overhaul.
